18 Claims.

The machine of the present invention is similar in its general structure to the machine set forth in my co-pending application Serial No. 192,332, filed February 24, 1938, but the present invention is directed primarily to an essentially diiferent method of constructing, mounting 'and actuating the gluing mechanism provided for the purpose of applying transverse glue lines to an intermittently advancing web of Cellophane, paper, fabric, or the like, all ofk which materials are included under the term web.

In the machine of the present invention, the glue pot and associated mechanisms are mounted upon a carriage which is intermittently moved back and forth beneath the web during the pauses in its advancement and so constructed as to apply closely spaced parallel glue lines to the web upon each traverse of the carriage, and provision is made for the adjustment of the gluing mechanism so as to permit severing from the web of strips of the desired length by means of a knife which cuts the web transversely between each pair of glue lines, the adjustment being suillciently accurate to permit such cutting even though the glue lines are spaced closely together.

Provision is also made for adjusting the length of web drawn out during each cycle of operation, and the diierent adjustments are so coordinated as to permit sections of web of the desired length to be severed in such a way as to provide individual wrappers each glued along the edge in close proximity to the line of severance and running transversely of the grain of the web, which is important in the subsequent use of the severed sections for the wrapping of boxes, cartons or the like by suitable wrapping mechanism, which, however, constitutes vno portion of the present invention. Provision is also made for adjusting the length of the gluing stroke so that the transverse glue lines will be of the intended length and occupy the intended positions with respect to the web.

The machine embodies mechanism for applyi'ng suitably spaced longitudinal glue lines at the desired points and of the desired length, so that the sheets or sections when severed and delivered from the machine will be suitably glued in the desired manner for wrapping purposes.

'I'he machine as a whole is built within a frame comprising upper side rails 2l which carry a sub-frame 2lil at the forward end. the sides .of which are connected by cross guide rods 2| and 22 and by an inverted T-bar 23, and farther to the rear by a cross bar |00, all of which connecting portions constitute functioning elements in the machine combination. Additional cross connections may Ibe provided, if necessary, to afford the required rigidity.

The frame is supported at its four corners upon legs 25 mounting casters 28, which permit themachineas awholetobeeasilymovedas occasion may require. The legs on each side are connected near their lower ends by lower side rails 21 each of which aords a point of 40 connection for the lower end of an upright bar 28 extending up to and connecting with the upper side rail 20 on the same side of the machine. The lower rail 21 provides support for a platform 29 on which is mounted a motor I0 which drives a pulley wheel Il by means of a belt I2.

The pulley wheel is mounted on a shaft u carryf ing a pinion 34 meshing with a spur gear Il, which arrangement provides a reducing train. thus enabling the spur gear to act as the driving center for the mechanism presently to be described.

The gear 35 is provided with a crank arm which is pivoted to the lower end of a rocker arm 81 carried by a rock shaft Il upon which is rigidly mounted an upper oscillating bar 39 which carries a rack bar Il provided on its outer upper edge with rack teeth Il. The rack bar connects with a head l2 which is adjustable upon the upper oscillating bar 39 to vary the stroke so of the rack bar which is the active element in advancing the 'web to the desired extent during each forward thrust of the rack bar, by

iengagement with the ratcheted pinion II on i ing transverse back and forth movements to the carriage which mounts the transverse gluing Q mechanism and which will presently be described in detail. A The web W is fed from a roll carried by -a 1 spindle 46, the ends of which are mounted within slotted brackets 41 carried by the forward legs 25 of the frame, 'and the web is rst guided beneath a roll 49 thence upwardly behind and l over a. tensioning roll I9, thence under the main feed roll 50 and over a tensioning pressure roll |thence forwardly around an adjusting roll 52 Q and forwardly over the main feed roll 50 and under pressure rollersections 53, which vbrings the web to the ponit of severance, which is effected by an oscillating shear blade 5l.

l The shaft of the roll 5| is carried at its ends ,within spring backed journal blocks 5|n (Fig. 12) jslldable within guide lugs 5| and adjustable fore and aft by spindles 5| mounting hand ,wheels Sid. Each spindle has a flat 5|e adapted lto register with the inner end of lan aperture in.

the journal block and allow theblock to advance under pressure of the spring, thus put- 3ting pressure on the roll 5|. but when the spindles are rotated the blocks will be retracted and lthe roll 5| drawn back from contact with the roll 50.

I The transverse gluelines are applied to the under face of the web portion extending between the rolls 5| and 52, and by providing for the ifore and aft adjustment of the roll 52 the length` of the web portion between the transverse glu- :ing line and the shear blade .can be regulated 1in harmony with the adjustment of the feeding stroke for the web, so that each cutting stroke of the shear blade will strike the web along a line between closely adjacent glue lines, thereby @22 and carries a glue pot or `fountain 5B partially closed on its top by a plate wall 51 hav- `ing a throatedaperture 58,' the walls of which extend below the intended level of the glue, adhesive, or other substance to be applied to the surface of the web. 'I'he glue pot or fountain is held in position upon the carriage by a screw 59, the upper end of which is threaded into a boss 60 in the base of the glue pot, thereby permitting easy removal of thepot from the carnage.

` The top plate wall 51 is provided with a'flange 6| which engages an overlapping flange 52 on a closing plate 53, which flanges are locked in closed relation by the beveled inner end of a plug 6| entered through a slot ,95 in the edge of the flange 672. The plug is carried by a pin 99 entered through the flange 5| and surrounded by a coil spring 51 bearing against the inner rear-edge Il engaging an undercut flange 99 exiending up from the rear wall of the glue Referring to Figs. 8 and 9, the closing plate 69 is provided near one side with depending hangers 10 each of which has entered therethrough a pointed bearing screw 1I, which pointsin commotion afford bearings for. a pintle 12 which mounts an oscillating frame 19 open on its lower side, and having a surrounding side wall flange 1l and an overlying top wall 15 provided in its center with an aperture 19 through which project the peripheries of two companion gluing wheels 11 which are slightly spaced apart to provide parallel glue lines when brought into contact vwith the web. The side wall flanges 1I converge inwardly toward the pintle 12 and terminate in heads 18 which surround the pintle, which aiIords a hardened bearing for the oscillation of the frame.

Between the heads 1s is located a head 1s upper side by an adjusting screw 94 entered through the upper wall of the pivoted frame 13 for adjusting the position of the frame relatively to the arm 90 which carries the glue rolls. The arm on its under side bears against a spring 95 which is supported by a bridge 95 extending across the lower portion of the oscillating frame y 13. The extreme end of the arm terminates in a notched block 81 having a beveled cam face IIB adapted to be engaged by a cam block 99 on the end of an adjusting thrust rod 90 which when thrust inwardly will depress the free end of the arm 90 with the glue rolls carried thereby so as to retract the glue rolls and disable their operation as occasionmay require.

The aperture 16 through which the glue rolls project is configured to afford extensions 9| the edges of which closely embrace the projecting peripheries of the respective glue rolls, and the end walls 92 of these apertures are inwardly beveled so as to afford inwardly projecting scraper edges 93 so disposed that they will alternately act as sorapers or gauges for limiting the amount of glue carried upwardly by the glue rolls as they are alternately rotated first in one direction and then in the other. By adjustment of the screw 84, the distance between these scraper edges and the peripheries of the glue rolls can be regulated to conform to the character of the glue or other substance being applied and the thickness of the coating desired.

'I'he plvoted oscillating frame 13 is provided on its inner upper edge with an extension 94, which hooks over the adjacent edge wall of the glue pot and carries an exterior depending arm 95 which amounts a roller 99 at its lower end.

The arm 90 and associated parts are normally Y projecting from the arm 95 and its upper end face of the flange, so that by drawing back the 1 arrangement permits the cam shoes to be adsecured to a screw 99 on the wall of the glue pot.

The roller 96 ls positioned to roll upon the under face of a cross bar |00 mounting cam shoes |0| each carried by a slide block |02, which justed to any desired position along the cross bar |00, the arrangement being such that when the roller 88 rides under either of the cam shoes it will be drawn down so as to depress the pivotedV arm 80 carrying the glue rolls, thereby retracting the same from contact with the web, which contact will only occurwhile the roll is traversing the unobstructed portion of the bar |00, which is supported at its ends from hanger brackets |03.

The glue rolls act against the pressure afv forded by the inverted T-shaped cross bar 28. which is provided with a facing strip |04 (Fig. 4) of soft rubber or other cushioning material which overlies the lower turn ot the web at the point where the glue rolls contact the same.

The means for reciprocating the carriage will now be described: As shown in Figs. l, 2 and 3, the carriage is shuttled back and forth by means of the endless cable 45 which is alternately moved in opposite directions by the oscillation oi.' the arm 43. 'I'he cable passes around a lower tensioning roller |05 mounted on the end of a pivl oted lever |08 the outer end of which is engaged by a spring |01 so as to impart tension on the lower part of the cable shown in Fig. 1. The two adjacent sections of the cable pass upwardly from the roller |05 and over the rollers |08 and |09 respectively in the adjacent frame rail 20, and thence inwardly and across the machine and around a roller located on the opposite side.

The transversely extending turns of the cable, as best shown in Fig. 4, pass through a guide member depending from the carriage, which guide member carries half cylindrical channeled guide lugs 2 so disposed as to maintain the turns of the cable against sagging below the intended plane of operation. Each of the transversely extending turns of the cable is provided with a stop block or button H3, which is of relatively small size and is normally adapted to travel freely through the space above the associated guide lug ||2, as indicated at the light in Fig. 4. The guide lugs coact with a centrally pivoted rocker arm ||4 provided at each end with a hooked linger which, when depressed as a recess in the wall oi the guide member and adapted to hold the rocker arm in either of its two positions of movement. The rocker arm ||4 is rocked at each end'of the range q! movement of the carriage by trip mechanisms best illustrated in Fig. 3. Each of these trip mechanisms comprises a vbell crank H8, the upper portion of which is in the form of a trip iinger ||T and the lower portion in the form of a depending taili piece H8. Each bell crank is carried by'a pivot il! located at the inner end of a bracket armk |20 projecting inwardly from the proximate side frame rail of the machine, the arrangement being duplicated as shown.

The trip finger III` is normally elevated by the pull of aspring |2|, .andthe trip finger normallyfs'tands inv position to cverlie and strike down 'proximate -end ofthe rocker arm ||4 when lthe carriage ismoved tothe end of its operating range., As shown in Fig. 3. one of the trip mechanisms is positioned to act upon one end oi 'the rocker arm, and the companion trip mechanism on the opposite side of the machine is positioned to act upon the other end of the rocker arm. Each trip mechanismy is positioned to coact with one of the two turns of the cable 4l and with the block or button ||3 carried thereby.

With the trip linger normally elevated as shown at the right in Fig. 3. and with the button ||8 moving to the right, and with the near end of the rocker arm elevated as in Fig. 4, the button will travel freely through the space above the channeled lug ||2 until it strikes under the tail ||8 on the trip member, which momentarily kicks down the trip finger ||1 and depresses the near hooked end of the rocker arm, so that on the return movement ot the button to the lei't it will engage the outer side of the depressed rocker arm tlnger and carry back the carriage with it to the left hand position indicated in dotted lines in Fig. 3. The carriage will then stand ln the left hand position until the button on the far turn of the cable performs a similar tripping operation in preparation for the shuttling-back of the carriage to the right. These shuttling operations are properly timed to impart the back and forth carriage movements during the intervals of rest in advance of the web, so that the glue lines will be applied during such intervals.

The mechanism for adjusting the roll 52 will now be described: The roll is carried upon a spindle |22 (Fig. 3) having at each end a roller |23, the right hand roller being journalled within a slide block |24 through which is entered an adjusting screw |25 having at its forward end a hand wheel |28. At each end of the spindle is a spur gear |21 meshing with an overhead rack |28, so that by operating the hand wheel the slide block can be adjusted with relation to the gauge plate |28, and the intermeshing of the gears with the racks at opposite ends of the roll 02 will maintain equality in the adjustment at each end and prevent binding or cramping.

The roll 50, as shown in Fig. 2, is grooved to receive stripper lingers |28b which prevent the leading edge of the web from passing down around the roll; and the roll 00 underliesv and coacts with the pressure roller sections I8, best shown in Fig. 3. These roller sections are mounted upon a shaft |29, and each roller section consists of a group of grooved members |80 which are adapted to be adjusted transversely by the engagement of ilns |0| depending from a rider |32 mounted upon a cross rod |88 and adapted to be held in adjusted position by a thumb screw |34, the arrangement being such as-to pemit the grooved roller sections to be so positioned as to afford clearance for the longitudinal glue lines and spaced sufficiently far apart to allow the transverseglue lines to pass between the roller sections without being contacted thereby.

The lower edges of the ilns I3| lie closely adjacent to the upper surface of the advancing web and terminate at a point closely adjacent the edge of the movable shear blade 54 which coacts with a fixed shear blade located below the web, as shown in Fig. 4. The movable shear blade is pivoted at one end and actuated by suitable connections with the driving train at regularly timed intervals, so that at each descent of the shear blade the web will be severed and the severed section carried forward upon an endless carrier |38 (Fig. l)

The longitudinal glue lines are applied to the under surface oi' the web by means of one or more gluing rollers |31 each Journalled within a glue pot |38.provided with a bracket |39 terminating in a grooved head |40 which bears against a hexagonal rockshaft |4| and is held in place by an L-shaped locking bar |42 pivoted to the bracket |39 and having a locking screw |43 enftered through its lower end and into a lug |44 depending from the bracket, so that by tightenin`g up the screw the glue pot will be locked upon the hexagonal rock shaft in the desired position, it being understood that a plurality of such glue pots may be employed. l

Therock shaft |4| carries an obliquely dis posed arm |45 having at its end a pivoted dog|48 adapted to be engaged by a block |41 adjustably mounted upon a segment |48 carried by an arm |49 xedly secured to the rock shaft 38, `the arrangement being such that with each down; ward oscillation of the block |41 the dog |48 will be engaged and rocked during the period of engagement, which may be varied by adjusting the block tor the desired position. This rocks the shaft |4| and elevates the glue pot and roller into contact with the web to apply a longitudinal glue line of the desired length, depending upon the period of engagement of the block with the dog.

In Fig. 11 I have showna modified form of mechanism for oscillating the rock shaft |4| which carries the glue pot or pots |38. In this instance the rock shaft is provided on its end witha segmental vplate |50 having an arcuate slot which, receives an adjustable pivot |52 at the upper end of a link |53, the lower end of which is pivoted to the short arm of a lever |54, the opposite end of which rides upon a cam disk |55 having a high side |56.

The cam disk is provided with arcuate slots |51 which receive locking pins |58 carried by cam segments |59 each of which has a cam face |60 registering with the high side of the cam disk and of the same concentric curvature, so that by adjusting the segments the effective lengths of the high cam surface can be increased or diminished to any desired degree, thereby permitting adjustment of the period during which the glue rollers will be elevated to contact the surface of the web. The cam disk and segmental plates are carried by a shaft |8| having thereon a sprocket wheel |82 driven by a sprocket chain |63 carried around a sprocket |84 on thev shaft which carries the gear 35 of the reducing train.

Operation In operation the various mechanisms are driven in timed relation by the motor 30 operating through the reducing gear mechanism which imparts regularly timed oscillations to lthe rock shaft 38. The shaft actuates the upper oscillating bar 39 and the rackbar 4f, so that, at each upward thrust of the rack bar, rotation will be imparted through the ratcheted gear 4|JL to the main feed roll 50. The length of the feeding stroke can be variedlwithin wide limits by the adjustment of the head 42 on the oscillating bar, and accuracy of this adjustment is required in order to measure off and sever web strips of the desired length. Immediately after the feeding movement of the roll 50, and while the web is at rest, the movable shear blade will descend and cut 0H a Web section of the intended length.

During the forward advance of the web and while the rock shaft 38 is moving in a counterlclockwise direction, the block |41 carried by the segment |48 will engage the dog |46 and impart glue line or lines of the desired length will be applied to the web. During the interval of rest, duplicate transverse glue lines will be applied to the web at the point where it is backed by the rubber facing strip on the'under side of the inverted T-shaped bar 23.

The back and forth movements of the transverse glue carriage 55 will be regularly effected by the cable and trip mechanism in the manner previously described. and the range of. these carriage movements will be uniform during each cycle of operations; but the length 'of the gluing contact may be regulated by the adjustment and spacing of the cam shoes |0|, since the transverse gluing rollers will be held depressed away from the web during the intervals of time while the roller 98 rides upon the cam shoes, and the tion to the gauge plate, the length of web between the point of application of the glue lines and the line of severance by the blade can be exactly computed, and since the shearblade operates at regular recurrent intervals it is necessary that the length of Vweb thus measured off shall either be equal to or an exact multiple of the length of web advanced by the feeding stroke imparted through the rack |4| Vto the feed roll 50. y

By maintaining a proper relationship between the adjustment of the web feeding stroke and the length of the web section between the gluing lines and the line of severance, it is possible to insure precision'in the cutting of the web sections which in each instance must be severed along a line intermediate the closely spaced parallel transverse glue lines, so that each severed section will have -a glue line along each of its edges, which glue lines will extend transversely of the grain of the web.

Although both the longitudinal and transverse glue lines are applied to a downwardly presented turn of the web surface, these glue lines will be presented on the upper surface of the web turn as it advances toward the pressure roll sections 53, but; by properly adjusting the grooves in said roll sections to straddle the glue lines, the danger of smearing will be' avoided.

The method of actuating the transverse glue carriage is one which insures the application of glue lines on each forward movement and each return movement of the carriage and a proper timing of these movements with relation to the intermittent feeding of the web, with proper intervals of rest for the carriage while the web is being advanced.

Although throughout the specication I have referred to the application of glue, it will be understood that this is intended to cover the application of any A-desired form of adherent or. other it the use of the machine solely to the application of glue.

Although the invention has been described in full detail, it will be understood that numerous changes or modifications in structure can be made without departing from the spirit of the invention.
